2005 BMW 320 Cd Sport

CarHunch analysed 114 real MOT records for the 2005 BMW 320 Cd Sport. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2005 BMW 320 CD Sport diesel has a first-time MOT pass rate of just 37%, nearly half the UK average of 80%, which signals serious reliability concerns for a buyer. The good news is that dangerous defects are absent from this cohort, so safety failures aren't the core issue—instead, these diesels are racking up roughly 0.86 failures per test, suggesting wear-related mechanical problems that accumulate with age.

At nearly 147,000 miles median mileage, these cars are well-used for their 19-year age, and that high-mileage diesel engine profile explains why repairs are frequent rather than catastrophic. Before buying one, get a thorough pre-purchase inspection focusing on the diesel injection system, turbo condition, and gearbox health—these are where BMW diesel costs tend to bite hardest.

What to check before buying a 2005 BMW 320 Cd Sport

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
